4x%5E2+%2B+4y%5E2+%2B+4y+=+15
4%28x%5E2+%2B+0x%29+%2B+4%28y%5E2+%2B+y%29+=+15
4%28x+%2B+0%29%5E2+%2B+4%28y+%2B+%281%2F2%29%29%5E2+=+15+%2B+1
4%28x+%2B+0%29%5E2+%2B+4%28y+%2B+%281%2F2%29%29%5E2+=+16
%28x+%2B+0%29%5E2+%2B+%28y+%2B+%281%2F2%29%29%5E2+=+4
a) This is a circle.
b) Does not open.
c) V(0,-0.5)
d) Axis of Symmetry: y=-0.5 and x=0
e) X-Intercept
%28x+%2B+0%29%5E2+%2B+%28y+%2B+%281%2F2%29%29%5E2+=+4
%28x+%2B+0%29%5E2+%2B+%280+%2B+%281%2F2%29%29%5E2+=+4
x%5E2+%2B+%281%2F4%29+=+4
x%5E2+=+15%2F4
x+=+%2B-+sqrt%2815%29%2F2
f) Y-Intercept
%280+%2B+0%29%5E2+%2B+%28y+%2B+%281%2F2%29%29%5E2+=+4
%28y+%2B+%281%2F2%29%29%5E2+=+4
y+%2B+%281%2F2%29+=+%2B-+2
y+=+-0.5+%2B-+2
You can fill in the table of values.
h) graph
